Redqueen v0.9.1 release

[bhlangonijr]

This is a bugfix release for RQ version 0.9:

- Found/fixed a potential memory leak at evaluator class (thanks to Valgrind );
- Fixed a bug at passed pawn evaluation;
- Used a smaller value for the pawn hash size;

This fixed version is ~6 Elo stronger mainly because of the bug at passed pawn evaluation.

Obs.: Sourceforge environment is stable now. Many people had problems to download RQ 0.9.

Source & linux64/win32 binaries: http://sourceforge.net/projects/redquee ... een-0.9.1/
svn tag: https://redqueenchess.svn.sourceforge.n ... ease-0.9.1

Thanks,

Missing dll's were included in the windows distribution.

I can't get Redqueen to use more than 1 thread no matter what setting I put in the "Threads" option. This is with Arena 3.0 and Jim Ablett's 64-bit Windows compile.

Any tips?

edit: I've also tried the official 32-bit Windows build with the same result..

Hi Martin, sorry for that RQ still doesn't support multi cores. The option is there for the future.

The funny thing is that I am currently working in the SMP version of RedQueen using the YBW algorithm. You can count with that in version 1.0 I plan to release in a couple of months.

Thanks,

Aha, this makes sense. I couldn't really remember it supporting more
than 1 thread, but then I saw the Thread parameter in the config panel.

Looking forward to the SMP Redqueen!

But first it will play in TCEC E.
